ib' all-whom It may concern: K

Be it known that I, MILTON F-INKLE, Gif-the city, county, and State-ofNewYork', have invented certain new end useful improvements in Spoolrrsor' Bobbin-Wind'ers'for Sewing-Mlachines; and 4l do'herehy declare thatthe following isii full, clear, and erect description of thesaine,reference-beinghad to the accompanying inivhich4 Figure Lis e i"lion, 'show-ing its application to a sewing-niechinej.; Fig, 2 isaside-viert of the same, Fig'. 3 is u plan, showing lthe spooleriii/'section Similar letters o t', refereiice'indicate corrcspcndingparts in the several tigu'rcas.

My invention relntes'to the driving of a,

` spooieror' oobbiuwinderwithou't a. band 'by the friction oif upullej-1 or roll attached to. the 'spindie oi the spooler and bearing agai ut the ily-wheelor other-wheel or pulley of the sewing-machine.

Y itI consists in a. certain mode oi' applying' the 'spooler or Winderto the sewingmiachine, which provides forits proper adjustmentrclativelyto the wheel or'pulley by u hich it is driven.

To enable others skilled in the art to make and usemy inventionJ willproceedto describe its construction and operationi "A 1s the frame orstock'of. the spoolcr, which Yoeri-ies all its movable p'erts,consisting oi a single piece of metal, thefurmof which is bestrepresen't ed-.:inFig.3. V Thisstock is boxed right through in threeplaces, es shown'in theabovementioned iigure-i-vizgin one place for thereception of the ina-iu. 'spindle B., in another for the reception'ofthe 'stein a of the movable center @,fan'd in a'third f or the receptionoi' the lti'xed horizontal pinpb,'attached to the stationery anu Eofvthe .sewing-machine, the three bores being parallel with euch other.The middic boregvhich receives the Astem a, is counterbored, es shownatc c in Fig. 3, for the reception oi' a spring, d, which is coi-led roundthe seid stein, and which presses against a. pin, e, insertedtransversely through the said stem Afor the purpose of draiving'thetnoifable center U toward 4the main spindle. i

l) is thelfriction roll`or pulleyseured 'to the' puter end ot' the -maiuspindle 13,-'hering` its Y drawings, forniing part of thisspecification,

` ont view, partly in Section, ofV a spooler constructed accord-ing tomy invenpcripherical surface oi' suitable form to -fiit against thesurface ci' the {ily-wheel F of the The fixed pin b is suitably arrangedto per-"1V mit the roll or pulley D, when the. spoolerg, is placed on.'the said pin, to come in contact with the wheel F. The `said pluisarrangedfff parallel `with the mein shaft G ofthe sewing machine, onwhich the wheel F is placed, and hence when thespooler is placed on itthe :nain spindleB will be parallel 4with the shaft oi' thesewing-machine. The backpart of the stockv A is tapped und tted Wi h aset-sciew,f, to

secure it' to the pin b, upon whichthe. stock is capable of swingingvertically, as well as moving longitudinally to adjust it inproper-rela` tion` to `the Wheel Fwhcn the said set-screw is unscrewed.When the stool: A hns been prop-v erly adjusted the placing oi' thespool or bobbin' H between the mainspiiidle and movable centercausesnthe pressure of the 'spring d, acting against the pin e, to forcethe movable cen- 'ter C against the spool or bobbin and hldtho letter.up to the main spindle B, andthe said i pressure, being transmittedthrough the spool or bobbin to the spindle 13,-presses the frictionVroll or pulleyl) against the wheel F, as shown vin Fig: 3 and in redoutline in Fig. 1, with sui- Aficient forcefor thelatter'to drive it..When the spool or bobbin isrcincved from between the main spinille andmovable lcenter G there is nothing to hold the roll or pulley D against'the wheel' F, and hence itworks itself free of the said wheel, asshownin black outline in Figi.

, By applying the spring d tor'serve the two purposes herein describedthespooler or Winder is brought to un operative: condition by the mereact of, putting in the b'obbin or spool,

withouttne trouble ofthrowing one bend or .Y
